I know this is a stretch, but how about a feature article about dropping BMW's awesome 4 cylinder diesel (the one from the 123d) into an E30!!

Would it even be possible to import an M47 (2.0L 4-cyl turbo diesel)? I'd love to put one in my E46 Touring (either the higher power one from the 123d, or even the "normal" one that goes in the 320d/120d)!
